Though alternative methods of controlling insects, rodents, insect pests, pathogens, microbes and weeds have been developed, pesticides could not be replaced. The prosperous role of pesticides in the management of insect pests and diseases is indisputable. However, its nature of non selective toxicity towards other organisms and deposition in the environment warrants the legislation of usage. Pesticide use raises a number of environmental concerns. Over 98 per cent of sprayed insecticides and 95 per cent of herbicides reach a destination other than their target species, including non-target species, air, water and soil. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them. Pesticides are one of the causes of water pollution and some pesticides are persistent organic pollutants and contribute to soil contamination. Detection of pesticide molecules in the food items from plant and animal origin become imperative for safe consumption of food. Pesticide residues are referred as quantities of persistent pesticide molecules that pollute the environment and food stuffs. Many pesticides are being highly stable and continue to kill the target and the host long after the application which is both advantageous and disadvantageous. Thus, the detection and assays of pesticide residues have significant role to know level of residual pesticide molecules. The present edition of volume attempted to consolidate significant advancement of research at worldwide on pesticide residues. The status of pesticide usage pattern and residue level in food from plant and animal origin at different regions are described in-depth in the chapters. The book comprises of twelve chapters in two different sections. The first section of the book described on pesticide residue in nine chapters. Apart from methods of analysis of pesticide residues in the food and soil, the chapters with latest research on removal of residual pesticides and residue control by different methods are included. The other aspect of pesticide residue is sample preparation for residue analysis. Though the advance instruments chromatography to mass spectrometry are available, the precision and fast analysis for detection of molecules is depending on the sample preparation methods. The chapters dealing with advance methods of sample preparation is also included in the volume. X Preface Metabolism of pesticides denotes that any foreign substance that enters in the living system and how it will be changed into non-toxic and thrown out due to the enzymatic activity and other mode of action. When chemical toxins applied to non- living substance (soil and water) that will lose the toxic principles by degradation process due to the action of biotic and abiotic factors. The time to nullify the toxicity is of prime importance and it vary depending upon the chemical molecule and environmental conditions. Thus the study on metabolites, degradation and accumulation of pesticides become more important for pesticide assays. The second section of this book volume described about these aspects in three chapters. I hope that this volume will provide an update on the state of pesticide science with relevance to pesticides residues and metabolism and will stimulate innovative and significant impact on researchers and students on the subject and go further in the line of research. I am grateful to all the authors who contributed their expertise towards the production of a precious volume. I am indebted to Professor K.Gunathilagaraj, Tamil Nadu Agricultural University, India for his inspiration and eminent guidance to hone my skills in editing. I acknowledge Dr. N. Chitra my wife, for her support and encouragement during the book chapters review process.
